TENDER FRAME.

Application filed June 30,

My invention relates to railway rolling stock and consists in an improved tender construction articularly adapted for use in connection with tenders of the Vanderbilt type in which a cylinder-like tank is mounted upon the tender underframe and terminates at a point s aced substantially from the front end sill 0 the underframe.

In such tenders there has been experienced considerable difficulty in arranging for the application of the tank valve by which the tank is connected to the locomotive. This valve is necessarily located at a level below the bottom ofthe tank and it must not in terfere with the drawbar structure nor with the truck frame or brake rigging or other parts carried on the truck frame which of course have considerable movement relative to the underframe due to the pivotal mounting of the underframe on the truck. The difiiculty has been increased in those tenders mounted on six wheel trucks equipped with clasp brakes and in which the drawbar structure involved a double pocket for a unit drawbar.

The object of my invention is to provide a water reservoir in the front end of the tender frame which is adapted to be connected to the tank and to a supply conduit leading to the locomotive and which is so positioned as to permit the truck to be located nearer to the end of the underframe than has been possible with earlier structures.

In the accompanying drawings which illustrate a selected embodiment of my invention- Figure 1 is a top view of the end of a tender underframe embodying my invention, portions of the truck being indicated in dotand-dash lines,

Figure 2 is a longitudinal vertical section taken on line 22 of Figure 1.

Figures 3 and 4 are vertical transverse sections taken on lines 3-3 and 4-4, respectively, of Figure 1.

The underframe comprises an end sill 1, spaced sills 2 extending rearwardly therefrom, a box-shaped bolster 3 extending transversely of sills 2, diagonal members 4 extending from said bolster outwardly to the ends of the end sill 1, and a plurality of members 5 and 6 forming drawbar pockets 7 for mounting a unit drawbar which connects the tender to an engine assembled therewith.

Intermediate the bolster 3 and the end sill 1927. Serial 110. 202,523.

1 are suitable vertical and horizontal webs 8 and 9 extending transversely of the center line of the underframe between sills 2 and formlng with the latter a box-shaped water reservoir 10 located at the rear of drawbar pockets 7 and substantially in the same plane as bolster 3. The upper wall 9 of reservoir 10 is provided with an inlet opening for connection to a conduit 11 leading from the water tank 12 which is carried upon the underframe. The space above reservoir 10 and the bottom of the forward portion 13 of the tender tank forms a compartment S which may be utilized for the locomotive stoker mechanism in the usual manner.

At each side of drawbar pocket 7 are suitable vertical and horizontal webs 14 and 15 extending forwardly from reservoir 10 to the end sill and forming additional water reservoirs 16, each provided with an outlet opening in its lower Wall 15 for mounting a fitting 25 connecting the reservoir with a tank valve 17 provided in the conduit 18 leading to the locomotive.

This structure eliminates the necessity of extending pipes straight back with an angle in the rear of the drawbar pocket in order to connect with the tank 12 and also provides for greater side clearance for the drawbar as the walls of the drawbar pockets can be spaced further from each other due to the fact that the pipes usually extending along the sides of the drawbar pockets and to the rear thereof are eliminated.

The truck includes a frame 19, with a transom 20, and an end transom 21, which is mounted upon the wheels 22 and carries brake rigging, a portion of which is shown at 23 and 24. It will be noted that the reservoir 1016 and the piping connected thereto easily clears all of these truck parts.

In the preferred form of my invention, the tender frame, or at least the portion referred to in the above description, is formed of a one-piece casting whereby a maximum amount of strength may be obtained with a given amount of metal and whereby the cost of labor for assemblin a built-up structure is avoided. and I a so eliminate the necessit for maintaining tight joints and avoiding the loosening of various connections which are formed in a built-up structure.

Obviously these particular advantages might be foregone in a built-up structure which would nevertheless retain the main advantage of my construction, and I contemplate the exclusive use of all such modifications in the details of my invention as are included within the scope of my claims.

I claim:

1. In a railway tender, an underframe, a water tank carrled thereon, there being a water reservoir located in said underframe near the end thereof and connected to said tank. 1

2. In a railway tender, an underframe provided with a. drawbar pocket a water tank carried on said underframe, there being a water reservoir located in. said underframe at the side of said pocket and connected to said tank.

3. In a railway tender, an underframe provided with a drawbar pocket, a water tank carried on said underframe, there being a water reservoir located in said underframe at the rear of said pocket and connected to said tank.

4. In a railway tender, an underframe provided with a drawbar pocket, a water tank carried on said underframe, there being a water reservoir located in said underframe at the rear of said pocket and at both sides thereof and connected to said tank.

5. In a railway tender, an underframe provided with a drawbar pocket, 2. Water tank carried on said underframe, there being a water reservoir located in said underframe extending from side to side of the underframe at the rear of said pocket and extending forwardly abreast of said pocket at each side of the latter and connected to said tank.

6. In a railway tender, an underframe, a tank mounted thereon, a water reservoir in front of said underframe, a conduit leading from said tank forwardly and downwardly to said reservoir, and a conduit leading from said reservoir for connection to an engine assembled with the tender.

7. In a railway tender, an underframe, a water tank mounted thereon, a stoker compartment in said tank, a. water reservoir 111 said underframe below said compartment, a conduit beneath said compartment leading from said tank to said reservoir, and a conduit leading from said reservoir and adapted to be connected to an engine assembled with the tender.

8. A tender underframe casting comprising a bolster, an end sill, and a water reservoir between said bolster and end sill and the main body thereof and spaced from each other transversely of the underframe.

11. A tender underframe casting comprising a box-shaved bolster and a box-shaped reservoir extending parallel with and located in front of and at substantially the same level as said bolster.

12. A tender underfranle casting having a portion adapted to mount a water tank and forming a water reservoir in front of and below the level of said portion.

13. A one-piece casting forming the end of a tender underframe and including a water reservoir extending transversely of the longitudinal center line of the underframe with a central opening in its upper wall for connection to a tank carried on an underframe, there being forward extensions on said reservoir on either side of said center line with individual openings in their lower walls for connection to tank valves leading to an engine with which the tender is assembled.

14. A one-piece casting forming an end of an underframe for a Vanderbilt type of tender and having a water reservoir near its end adapted to be connected to the tank mounted on the underframe.

15. In a one-piece tender underframe casting, spaced longitudinal sills, a bolster between said sills, an end sill extendingbeyond said sills, diagonal braces outside of said longitudinal sills between the ends of said bolster and the ends of said end sill, and vertical and horizontal webs forming a water reservoir between said sills and said bolster.

In testimony whereof I hereunto afiix my signature this 27 day of June, 1927.

JOHN A. MCCORMICK.
